Thanksgiving is meant to be a time for gathering, cooking and enjoying a full house. In many Boston homes, however, the day after Thanksgiving has earned an unfortunate nickname. Brown Friday is one of the busiest plumbing days of the year, when overloaded drains, backed-up toilets and sewer issues turn holiday celebrations into emergencies.

With colder weather settling in and more people using the plumbing system at once, even a well-maintained home can experience problems. A little preparation before the holiday rush can help reduce the risk of an unpleasant surprise.

What causes Brown Friday plumbing problems

Brown Friday happens when plumbing systems are pushed beyond their normal limits. Extra guests, heavier cooking and colder temperatures can all play a role.

Increased drain usage

Thanksgiving meals create more waste than usual. Grease, food scraps and starchy leftovers often make their way into sinks and garbage disposals. Over time, these materials cling to pipe walls and restrict water flow.

Overworked toilets

More people in the home means toilets are flushed far more often than normal. Older plumbing systems and partially blocked drain lines may struggle to keep up with the added demand.

Cold weather impacts

Boston’s colder temperatures can slow water movement and affect pipes that are already vulnerable. When combined with heavy usage, small issues can quickly become full backups.

Common mistakes that lead to holiday plumbing emergencies

Many Brown Friday calls are caused by habits homeowners do not realize are risky.

Pouring grease down the drain

Grease may go down as a liquid, but it cools and hardens inside pipes. This creates a sticky buildup that traps food and debris.

Treating the toilet like a trash can

Paper towels, wipes and other non-flushable items often cause immediate clogs. Even products labeled as flushable can create problems in residential plumbing systems.

Ignoring slow drains before guests arrive

A slow drain is often an early warning sign. When ignored, the added holiday demand can push the system past its limit.

What homeowners can do before Thanksgiving

A few proactive steps can help reduce the risk of plumbing trouble during the holiday.

Be mindful of what goes down the drain

Scrape plates into the trash, dispose of grease in sealed containers and avoid overloading the garbage disposal.

Spread out water usage

Encourage guests to stagger showers and laundry when possible. This reduces strain on the plumbing system.

Address small issues early

If drains are slow, toilets gurgle or unpleasant odors are present, these issues should be checked before hosting guests.

These steps can help, but they cannot correct underlying plumbing problems.
